EVAPORATING VESSEL.

Specification of Letters Patent. Patented June 27, 191L Application filed November 14, 19170. Serial No. 592,204.

To all whom 'if may concern:

Be it known that I, lVARwrcii GUY Barn, a citizen of the United States, residing at- Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Evaporating Vessels, of which t-he following is a full, clear, and exact description.

rl`his invention relates to evaporating vessels adapted for use in connection with pipe systems of heating by steam, hot water, ctc., such as are in common use, particularly in hot houses or places ot like nat-ure where the humidity oi' the air or the diffusion of chemicals, etc., may be effectively carried on and controlled through evaporation.

The invention consists of a vessel adapted to be clamped to a heating pipe at any desired place inthe lengththereof, one side being recessed to `snugly fit the exterior snrface of the pipe and this side provided. with a longitudinal slot or aperture through which the surfaceof the heating pipe is exposed to the interior of the vessel, the surfaces oit which adjacent to the aperture conform closely to the periphery of the heatiiio` pipe, due allowance being made for the pre?- erable use ot sheet asbestos or other suitable packing material to form a tight joint all around the aperture.

The invention further consists of a detachable device for clamping the vessel to the heating pipe ofsuch nature` to admit. of the attachment or removal oit' the vessel to any existing pipe section, of, suitable length, without its having to be slipped over or ofi the end of the pipe section, and regardless of the presence of other fittings or connections affecting t-he longitudinal sur- .tace of the pipe. The preferred form of this clamping device consists of lugs on the sides of the vessel, engaged by hooks on the free ends ot a U-shapcd clamping yoke which passes around'the pipe and is provided with aset screw or other suitable device, at its closed central portion, which bears-against the heating pipe and draws the vessel into close contact therewith.

Many dil'l'crcnt kinds of evaporating vessels are now in use to etlcct the-purpose of this invention, but all have more or less o bjectionable features which it is sought in this to overcome. For instance there lis one [form in which the vessel and pipe are cast integral. This is very effective in permitting the contents ot the vessel to come into direct-I contact with the heating surface of the pipe, but it has the disadvantage of `having to be built directly into the pipe system and when so placed may not readily be changed to another position, however desirable, without expensive alterations of the system and the discontinuance'of its use durlng such alterations. Another form of vessel is removably connected to the pipes. but it has a closed or tight bottom whichprevents direct contact of the contents of the vessel with the surface of the pipe and is a less efi'ective evaporator because of the interposition of an additional thickness of metal between said contents andthe surface of the heating pipe.

In the accompanying drawing which illus- I trates a general `form and relative assemblage of the details of the invention preferred at this time, Figure 1 is a-vertical longitudinal section through the' evaporating vessel and clamping device on the line .1-1 of Figfl, the heating pipe being shown by dotted lines. Fig. 2 is a view of the same partly in vertical transverse section on the line 2-2 ot Fig. l, the clamping lvoke being shown in full side elevation. Fig. 3 is a perspective view of .the evaporationg vessel attached to a line of heating pipe. Fig. 4 illustrates a modified form of the invention. v A is the evaporating vessel, preferably rectangular, and of cast metal, with a rounded depression along one side/to fit snugly upon the surface of a heating pipe B, and having alongitudinal aperture a through the depressed side to expose the surface of said pipe inside the vessel.y The side Walls are thickened along the edges of the aperture to form broad bearing surfaces a and the inner end flanges a3, are reinforced by lugs at at the ends of the aperture.

C is a sheet of asbestos cardboard or other suitable packing used between the vessels" base flanges and the pipe to form a tight joint, this packing being longitudinally apertured to correspond with the open side of the vessel next the pipe.

D, D are lugs on the sides of the vessel, and E the clamping yoke engaging said lugs, with the hooks e at its free ends. This yoke has a central boss e and at each side of this boss it. is reinforced by ribs e2.

F is a clamping screw which passing through the boss e and bearing against the pipe holds the vessel securely in position thereon. The preferable form of the vessel is that adapted for horizontal pipes, as shown in Figs. l, 2 and 3, and previously described, but it may 'alsobe adapted for vertical or otherwise positioned pipes, as illustrated by the modified form of Fig. 4.

Having thus described my invention, what y pipe is exposed inside the vessel.

n 3. The combination of a vessel adapted-to fit against the surface of having an aperture through its side adjacent to saidv pipe whereby the surface of the pipe is exposed within the vessel, and means for detachably securing the vessel to the pipe.

4. The combination of fit against the surface of a heating pipe and having projecting lugs formed on the sides thereof, with a U-shaped clamping yoke adapted to embrace the pipe, and providedwith hooks at its free ends to engage the lugs on thel sides of the vessel, with means for tightening the clamping yoke to draw the vessel into close Contact with the pipe.

5. The combination of a vessel adapted to lit against the surface of a heating pipe and --having an aperture through the side adjacent to said pipe,

rejecting lugs on the sides of the vessel, an a clamping yoke passing a heating pipe and'- a vessel adapted to around the opposite side of the pipe and havinghooks which engage the lugs on the vessel, with means for regulating'the clamping pressure of the yoke on the vessel and heating pipe.

6. The combination of a vessel recessed at one side to fit against the surface of a heating pipe, and apertured through said side, projecting lugs on thesides of the vessel, and a- U-shaped clamping yoke passing around the opposite side of said pipe and having hooks at its free extremities which engage the lugs on the vessel and provided with a set screw which bears on said pipe.

7. The combination of a vessel adapted to fit against the surface of a heating pipe, with a U-shaped yoke adapted to pass around the opposite side of said pipel and engage the vessel with its free ends, with means whereby pressure may be exerted by the yoke upon -the pipe to clamp the vessel and pipe securely together.-

8. The combination of a heating pipe, a vessel recessed at one side vtoiit upon the surface of the heating pipe, and apertured through said side whereby the surface of said pipe is exposed within the vessel, a strip of packing between the abutting edges of the vessel and said pipe apertured to correspond with the side of the vessel, with means for detachably clamping t-he vessel and pipe securely upon the packin strip.

In testimony whereor, I hereunto ahx my signature in the presence of two witnesses.
